Dan (rank) - Modern Usage in Go

Modern Usage in Go

Traditionally, the level of go players has been defined using kyu and dan ranks. Kyu ranks are considered student ranks, whilst dan ranks are considered master ranks. Especially in amateur play, these ranks facilitate the handicapping system, with a difference of one rank roughly corresponding to one free move at the beginning of the game. With the ready availability of calculators and computers, rating systems have been introduced. In such systems, a rating is rigorously calculated on the basis of game results.

Dan (abbreviated online as "d") ranks are for advanced players. Although many organizations let players choose their own kyu rank to a certain extent, dan ranks are often regulated. This means that players will have to show good results in tournaments or pass exams to be awarded a dan rank. Serious students of the game will often strive to attain a dan rank. Dan ranks are generally available up to about 7th dan; professional player ranks go up to 9th dan.
